Yeah, it's quite possible we won't see Craig and Bridget as R&K again (
I'll never give up on it, entirely), but I hope we will at least see them on-screen together in different roles in the future.
Like Ben Browder and Claudia Black from Farscape, they played John and Aeryn for 4 years + a mini-series (one of the greatest TV couples of all-time, IMHO), then they played alongside each other again in Stargate SG-1 for two seasons!
